STAINLESS STEEL FOR THE PREPARATION OF THREADED WIRE MAINLY TIRE REINFORCED THREAD AND PROCEDURE FOR OBTAINING SUCH THREAD.

摘要

THE INVENTION CONSISTS OF A PROCESS OF MANUFACTURE OF TREATED WIRE, MAINLY USED AS REINFORCEMENT OF TIRES, WITH A DIAMETER LOWER THAN 0.3 MM, BY SHARPENING A BASIC MACHINE WIRE WITH A DIAMETER OVER 5 MM OR A BASE WIRE PRIOR TO A STEEL THAT RESPONDS TO THE FOLLOWING PONDERAL COMPOSITION: - CARBON 40.10 SUP, -3% - NITROGEN 40.10 -3%, WHERE CARBON AND N ITROGEN FULFILL THE RELATIONSHIP C + N 50.10 -3%, - 0.2% SILICON 1.0% - 0.2% MANGANESE 5% - 9% NICKEL 12% - 15% CHROME 20% - 1.5% COPPER 4% - SULF 10.10 -3% - PHOSPHORUS 0.050% - 40.10 -4% TOTAL OXYGEN 120.10 -4% - 0.1.10 -4% ALUMINUM 20.10 -4% - MAGNESIUM 5.10 4% - 0.1.10 -4% CALCIUM 5.10 -4% - TITANIUM 50.10 SUP, -4% - IMPURITIES INHERENT TO THE MANUFACTURING PROCESS . STEEL IN WHICH THE INCLUSIONS OF OXIDES, IN THE FORM OF VITREAS MIXTURES, RESPOND TO THE FOLLOWING PONDERAL PROPORTIONS: 30% SIO 2 65% - 5% MNO 40% - 1% CAO 30% - 0% MGO 10% - 3% AL2 O 3 25% - 0% CR 2 O 3 10%.
